WH I FFLETREE.

' SPECIFICATION forming part of Letters Patent No. 283,274, dated August 14, 18 83. I Application filed May 252 1883. (No model.)

To all-whom it may concern:

Be it known that I, EDWARD PALMER, of West Garland, in the county of Penobscot, and in the State of Maine, have invented certain new and useful Improvements in Whiffletrees; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and tothe letters of reference marked thereon, making a part of this specification.

My invention relates to the attachment of whiflietrees to cross-bars of vehicles; and its object is to prevent rattling of the parts, especially when they come loose by long and Fonstant wear, as will be hereinafter fully set orth.

In the accompanying drawings, making part of this specification, Figure 1 representsa perspective, and Fig. 2 a central vertical crosssection, of my invention.

In the figures, A represents a whiiiietree of any ordinary construction, and B the cross-bar to which the whiffletree is usually attached.

0 represents a bow-spring, its ends being interposed between the whiffietree and the bar. Interposed between thetwo ends of the spring is an anti-friction roller, (1, made of any suit able shape, but of small dimensions, so as not to remove the whifiietree too far from the bar.

e represents a bolt which passes down through the center of the whiffletree, the roller and the bar, and through the springs, near their ends. I This bolt is provided with a suitable adjusting and tightening nut at its lower end.

In adjusting the parts together the two ends of the spring are placed upon the bar B, with the roller d interposed between them. The whiflietree is placed upon the upper end or leaf of the spring, and the bolt 6 is then passed down through the several parts and secured in place by its nut. The bow of the spring remains in rear of the whiffletree and bar. As wear takes place the upper end or leaf of the spring bears the whiffletree upward, and thus prevents any rattle of the same. The roller allows the parts to work freely when they are tightened up closely'by the nut.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is I The combination of the bar B, whiffietrec A, bow-spring O, with the interposed roller (1, and binding-bolt e, the several parts being constructed and connected, substantially as and for the purposes described.

. In testimony whereof I affix my signature, in presence of two witnesses, this 22d day of September, 1882.

. EDWVARD PALMER. \Vitnesses:
